问题描述

我正在使用 Windows Phone 8 应用程序，但找不到如何获取坐标表单地址.问题是，我有我的坐标，我需要计算我和某个地址之间的距离.

I'm working on windows phone 8 app, but i can't find, how to get coordinates form address. Problem is, i have my coordiantes, and i need to calculate distance between me and some address.

windows phone 8 没有那么多文档，所以请帮帮我.

推荐答案

您要查找的内容称为地理编码":将地址转换为地理坐标.

What you're looking for is called "geocoding": Converting an address to GeoCoordinate.

正如之前提到的，您可以在 WP7 上使用 Google 和 Bing 来实现这一目标.在 windows phone 8 上，作为框架的一部分支持地理编码和反向地理编码.您可以在这篇诺基亚介绍文章中阅读地理编码概述在地理编码"下)和更全面的概述 在另一篇诺基亚文章中.

As was mentioned before you can use Google and Bing on WP7 to achieve that. On windows phone 8 Geocoding and Reverse Geocoding are supported as part of the framework. You can read an overview to GeoCoding at this Nokia intro article (under "Geocoding") and a more comprehensive overview at this other Nokia article.

以下是将地址转换为坐标的地理编码示例:

Here's an example of Geocoding converting from an address to coordinates:

private void Maps_GeoCoding(object sender, RoutedEventArgs e)
{
    GeocodeQuery query = new GeocodeQuery()
    {
        GeoCoordinate = new GeoCoordinate(0, 0),
        SearchTerm = "Ferry Building, San-Francisco"
    };
     query.QueryCompleted += query_QueryCompleted;
    query.QueryAsync();
}

void query_QueryCompleted(object sender, QueryCompletedEventArgs<IList<MapLocation>> e)
{
    StringBuilder sb = new StringBuilder();
    sb.AppendLine("Ferry Building Geocoding results...");
    foreach (var item in e.Result)
    {
        sb.AppendLine(item.GeoCoordinate.ToString());
        sb.AppendLine(item.Information.Name);
        sb.AppendLine(item.Information.Description);
        sb.AppendLine(item.Information.Address.BuildingFloor);
        sb.AppendLine(item.Information.Address.BuildingName);
        sb.AppendLine(item.Information.Address.BuildingRoom);
        sb.AppendLine(item.Information.Address.BuildingZone);
        sb.AppendLine(item.Information.Address.City);
        sb.AppendLine(item.Information.Address.Continent);
        sb.AppendLine(item.Information.Address.Country);
        sb.AppendLine(item.Information.Address.CountryCode);
        sb.AppendLine(item.Information.Address.County);
        sb.AppendLine(item.Information.Address.District);
        sb.AppendLine(item.Information.Address.HouseNumber);
        sb.AppendLine(item.Information.Address.Neighborhood);
        sb.AppendLine(item.Information.Address.PostalCode);
        sb.AppendLine(item.Information.Address.Province);
        sb.AppendLine(item.Information.Address.State);
        sb.AppendLine(item.Information.Address.StateCode);
        sb.AppendLine(item.Information.Address.Street);
        sb.AppendLine(item.Information.Address.Township);
    }
    MessageBox.Show(sb.ToString());
}

当我在 WP8 上运行此代码片段时，我收到以下消息框:
